[i] N2 progeny of D2B6F1 ApcMin /+ parents #5, #6, and #7 from Table 1 were classified according to strain background as well as genotype and phenotype at the Mom1 andMom2 loci, respectively. Average polyp numbers are shown ± standard deviation. The number of offspring in each group is shown in parentheses. P values were determined by the two sample t-test.
